\section*{Preface}
This report, \textit{Irreversibility of combustion, heat and mass transfer} is the Master's thesis of Pedram Nadim. The report was produced at the Department of Energy and Process Engineering at the Norwegian University of Science and Technology in Trondheim, Norway. The report was written as the final thesis for the 5-year Master of Science Degree in the field of Energy and Environmental Engineering.

The purpose of this thesis is to quantify the sources of irreversibility in turbulent flames in order to gain a better understanding of combustion, and how to increase the exergetic efficiency in the combustion chamber.

I would not have been able to write this thesis without help from my professors, family and fellow students. First of all I would like to thank my supervisor Ivar S. Ertesvåg for helping me understand this complex subject. He has been enthusiastic and helpful whenever I have asked for advice. I also want to thank Professor J.Y. Chen at University of California Berkeley for introducing me to the intriguing research field of combustion through his courses, and inspiring me to continue working in this field. I would like to thank my parents and my sister for being good role models and for their help and support thorughout my academic career. I would also like to thank prof Homayoon Kazerooni and prof Tim D'Orazio for giving me helpful academic advice during my stay abroad. \\ \\ \\ \\ \\
